“…[e.g.,19,38,39,52,76,81,82,95] In the current study, the initial analyses supported these past findings in that as age increased, perceived life satisfaction also increased, and catastrophizing, depression, pain intensity, and pain interference decreased. However, when catastrophizing and depression were included in the multivariate model as predictor variables, these age-related findings became non-significant, suggesting that the pain-related dependent variables were more strongly associated with catastrophizing and depression than with age per se.…”

Rural residency and low socioeconomic status (SES) are associated with increased likelihood of chronic pain. Other demographics are also differentially associated with the experience of pain. This study examines the relations between demographic and pain-related variables in a virtually unstudied population of rural Alabama chronic pain patients. One-hundred-and-fifteen patients completed validated measures of pain catastrophizing, depression, pain intensity, pain interference, perceived disability, and life satisfaction. Average age of study participants was 52-years, 79% were female, 74% were African-American, 72% reported annual income between 00,000-12,999, and 61% were unemployed. Although average years of reported education was 12.26, reading level percentile (primary literacy indicant) was 17.33. Cross-sectional multivariate and univariate analyses were conducted to examine associations among demographic and psychosocial variables in relation to various pre-treatment pain-related variables. The mediating role of pain catastrophizing and depression was investigated. Results indicate that race was significantly associated with pain intensity and pain interference, such that African-Americans reported higher scores than White-Americans. Pain catastrophizing was uniquely associated with pain intensity, pain interference, and perceived disability; depression was uniquely associated with pain interference, and life satisfaction. Pain catastrophizing mediated the relation between primary literacy and pain intensity; age effects were differentially mediated by either pain catastrophizing or depression. These analyses provide insight into the specific demographic and psychosocial factors associated with chronic pain in a low-literacy, low-SES rural population.

“…Several authors have used taxonomic methodologies to identify subgroups of patients with chronic pain on the basis of the previously mentioned factors. 5,12,14,37,46,66,73,76 Two subgroups or clusters have been consistently identified across multiple studies. The first cluster is classically characterized by high pain outcome measures (ie, high pain severity, depression, and disability).…”

“…64,74 In addition, a third cluster of patients with chronic pain reflects an intermediate clinical pain outcomes profile (ie, medium pain severity, depression, and disability). 12,14,35,36 The evidence is unclear whether patients with chronic pain within the same cluster have similar pain outcome measures when stratified by demographic variables such as race, age, and gender. This is particularly salient, because there is convincing evidence that racial and ethnic minorities, older people, and women experience pain differently, which might lead to worse outcomes.…”

“…(34) Furthermore, according to some studies, men and women tend to use different coping styles when in pain. (34)(35)(36) The lack of a standardised definition for PLP and heterogeneity among the patient groups recruited by the various reports hinder efforts to make comparisons across studies. For instance, in the study by Bosmans et al, PLP was defined as daily pain, and consequently, patients with less frequent occurrence of symptoms were excluded.…”

Singapore Med J 2013; 54(2) : 75 O r i g i n a l A r tic le INTRODUCTIONPhantom limb complex is a term used to describe phantom limb sensations (PLS), phantom limb pain (PLP) and/or stump pain (SP).PLS is defined as any sensation, other than pain, in the absent limb. PLP is any painful sensation referred to the absent limb, while SP is pain localised in the stump. These elements often coexist in patients and may be difficult to differentiate.(1,2) Phantom limb complex, which is not an uncommon phenomenon, can be chronic and distressing to patients.Based on the current literature, the reported incidences of PLP vary from 47%-79%.
